Acronis 11 incremental backups take 12 hours
I recently installed 11 after upgrading our domain servers to VM servers. The doamain controller and exchange server are the only server being backed up by Acronis. We are using 2 standalone servers as the acronis backup servers, they replicate to each other. We have the vaults located on 2 4TB netgear ready nas appliances. An incremental backup of approximately 7 GB's takes 12 hours to run, that doesn't include the replication, because that only works half the time. a full backup of these two servers takes over two days to backup, both servers combined are 800 GB's full backup. Any suggestions? I called acronis but the technician spent 45 minutes on it and all he did is remove the vaults and add them again which actually made them slower. If this software weren't so expensive I would have scrapped it by now.
Shouldn't take that long. Are you running deduplication as well?
Do you have a spare large-capacity USB external drive to try? (That might help eliminate the Netgears as a possible bottleneck)
We experience some pretty slow incremental backups too. Its not all the time but when its slow, it crawls. We have one separate Acronis server with everything on GB Ethernet only ours is not replicating. Data recovery is really what takes the longest. We firmly believe this is a software issue, not a networking issue on our end.
Hello Brendan!
Thank you for using Acronis products.
Please try to make another incremental backup to another storage device (an internal HDD for example) and check if you have the same issue.
While the backup task runs, if there is any problem it will appear at Acronis Console - logs - events
If there is an issue with backing up, please contact Acronis Customer Central with a reference to this article and the following diagnostic information:
- AcronisInfo Utility;
- The operation log of the product;
- Wireshark logs. See Collecting PCAP Logs.
If there is something else I can do for you, please let me know.
Thank you, have a good day!
Hi Brendan
Backing up 800GB over 2 days (48 hours) means you are transferring at around 4.7MB/s which is VERY slow for an image backup.
I would also suggest looking into the following:
- Copy files from your server to the backup destination viw Windows explorer and ensure there is no speed issues
- Ensure you are running an image backup and not file backup (Image backups are generally faster than files backups as small files will place allot of I/O on your HDD/RAID system and transfer speeds will drop dramatically so when doing the copy testing above ensure you are coping the same files and not just large files that generally tell you the fastest any system can run at)
- Check your CPU usage on your systems, especially if running and backing upto storage node, if running a single server only I would suggest looking into backing upto an unmanaged vault as using a managed (storage node) for a single server might be overkill and not required.
Please let us know how you go and what you find.
